Corporate history
Following our founding in 1946, we started to manufacture standard series of steel flanges in 1963. However,in 1984, we changed our strategy to focus our business on high-end products. Since then, we have delivered various special forged components manufactured by our experienced and unique technologies not only to domestic markets but also to all over the world. Recently we have been challenging new products by means of utilizing our cultivated technologies.
